The following are some excerpts from the Writings and other research about the five-pointed star:

More on the five pointed star(s):

Briefly, such are the least of the mysteries of the composition of the
Greatest Name upon the stone of the Divine ring.

Observe also that the three planes represent the world of God, the
World of Command, and the World of Creation, which are the sources of
the signs. The world of God is the source of Glorious Bounty; the world
of Command is the pure and luminous Mirror which depends upon the Sun
of Truth; and the world of Creation is the source of the acquisition of
Lights which is due to the Supreme Conjunction: To take from God; to
give to the creatures.

In brief: the true "Ba," which is the universal Reality, once descended
and distributed into the third degree from the Supreme Grade, to the
inferior creatures, becomes the collector and creator of all the
worlds.

Upon the horizon of Eternal Glory two luminous stars have arisen in
brilliance: one to the right and one to the left. This supreme mystery
is the two diagrams placed to the right and to the left of the Greatest
Name upon the stone of the noble ring: this is the mystery of the
appearance of the Beauty of Abha and of the Supreme Highness (the Bab).
And though these two diagrams at the right and the left have the form
of stars, they also represent the body of man, with the head, the two
arms and the two legs, since this diagram has five points.

(Compilations, Baha'i Scriptures, p. 479)

"... Strictly speaking the five-pointed star is the symbol of our
Faith, as used by the Báb and explained by Him. But the Guardian does
not feel it is wise or necessary to complicate our explanation of the
Temple by adding this."

(From a letter written on behalf of the Guardian to an individual
believer, October 28, 1949: U.S. Supplement to Bahá'í News, No. 50,
p.

(Compilations, Lights of Guidance, p. 109)

The two five pointed stars on both sides of the emblem represent the
human body: a head, two hands and two feet. These two stars represent
the twin Manifestation of God in this Day. Their advent is the
fulfillment of all the writings of God's prophets in bygone ages, Who,
emphatically, repeatedly and often, in a language clearer than the
light of sun, assured mankind of the undoubted appearance of these Twin
Luminaries, Who would rescue the world from the fetters of prejudice
and the dictates of self.

(Abu'l-Qasim Faizi, An Explanation of the Greatest Name, p. 19)

John Walbridge, in an article on this Tablet in _Sacred Acts..._ pages
165-69, wrote "_Haykal_ is a loan word in Arabic. Its Hebrew cognate
_hek'l_ means 'temple', particularly the Jerusalem temple. In Arabic,
in addition to meaning a Jewish or Christian temple, it means the body
or form of something, particularly the human body or something large.
In the Báb's usage, a _haykal_ is a talisman, particularly one in the
form of a five-pointed star, which traditions represents the human
body. In the Súratu'l-Haykal the primary sense of _haykal_ is the
human
body, particularly the body of the Manifestation of God, but the
meaning 'temple' is also present." Haykal can also mean building,
altar, skeleton, frame, or human body. In this Tablet, then, "haykal"
seems to refer to the human temple or body, specifically the body of
the Manifestation of God.
